The people who hoard food just amaze me. They had a woman who would still eat out dated food. She had stacks of yogurt in her fridge and it was over 6 months old but she still ate it. Even when they tried to throw away a rotten pumpkin she stopped them and said she wanted the seeds. I'm assumng her issue come from not having enough food at one point in her life.
My grandmother was like this with food for awhile but she wouldn't eat it she would just buy and buy and buy and not throw out anything I took charge one day and threw everything out. She was less than thrilled with me for a few days but was thankful I did it. She knew it had to be done but was so afraid of not having money or being able to buy anything she would just keep it.
